The funnel is everything that flows into Lorca. Everything "Lorca Knew."
A second image would be everything surrounding Lorca, "Lorca y sus circunstancias."
A third conception is everything based on Lorca, flowing out of him.
So there are three conceptions of Lorca, past, present, and future. Apart from the idea of "Lorca, himself." That makes four.
You can talk about what traditions Lorca took from the past (the funnel).
You can talk about Lorca in his own historical context, his historical present.
Or Lorca's after-life.
So an example of the first: Lorca and Góngora.
2: Lorca and Dalí.
3: Lorca and Jack Spicer.
4: An analysis of a work by Lorca himself.
